到目前为止，这听起来很棒。50°C，日本电容器，80+金，可配制风扇，7年保修，优秀！单个12 V轨道不是我看来的卖点，我宁愿在这个尺寸范围内的一个单位上看到至少两个。它并不像具有更大单位的问题那么大。

Here we have a few interesting things, the first of which are the ripple and regulation numbers. The ATX spec requires 5% regulation on the three primary rails, PC Power and Cooling’s 3% is a solid improvement over that, but not necessarily epic. I expect that this PSU will do rather better than that. The 1% ripple number is the ATX spec (except for 3.3 V, which is allowed ~1.5%), I’d prefer to see 0.5% or less personally. The 1% mark may be difficult to hit on the 3.3 V rail, DC-DC designs often have a rough time of it.
电缆明智我们有一个很好的选择，我非常希望两个CPU电力电缆并不是硬连线。
The MTBF of 100,000 hours (that’s >11 years) is perhaps a bit ambitious, but who knows. With a seven year warranty PC Power and Cooling is backing it up well.
Next, pictures!
